Energy density

The purpose of this lab was to create an experiment to test samples of plastic-like cylinders, to see if the different masses had an effect on the density of the objects. The original hypothesis was if the mass of the substance increased there would be no effect on its density. As seen in the data analysis, the average density was 1.7 (g/mL), with only a negligible 0.1 (g/mL) difference across all four masses of the substance. Furthermore in the data, if the mass of the substance increased, the

how salt concentration and density affects floating objects. The control is water not having salt, and the constant variables are the amount of water in each cup and the objects. The independent variable is the amount of salt added in the cup. The dependent variable is the height of the water and the density of the water. Background Research How do objects float on water? The density and buoyancy are properties of matter that determine how objects float on water. Density shows the amount of mass in

presented were a cylinder, cube, and a rectangular prism. Through examining the physical properties of the objects the best possibility in finding the substance of each object was through finding the density. Density is defined by a physical property between the mass and the space taken up by the substance. Density is found by using the formula mass divided by volume. Identifying the mass and the volume of each object will help to identify if the objects are made of the same material. Through the initial

alcohol. 8. Calculate the densities of both the water and the isopropyl alcohol and record in Data Table 4. 9. The accepted value for the density of water is 1 g/mL and the accepted density for isopropyl alcohol is 0.786 g/mL. Determine the percent error between your calculated densities and the accepted values for both water and isopropyl alcohol. Record the percent error in Data Table 4.

vertical U tube of uniform cross section contains mercury in both of its arms. A glycerine (d = 1.3 g/cm3) column of length 10cm is introduced into one of the arms. Oil of density 0.8g/cm3 is poured in the other arm until the upper surfaces of the oil and glycerine are in the same horizontal level. Find the length of oil column. Density of mercury is 13.6 g/cm3. (9.6cm) 2. Two communicating cylindrical tubes contain mercury. The diameter of one vessel is four times larger than the

The Relationship Between Density and Sugar Content Danielle Shaub Partners: Emily Alexander, Bill Dempsey, Shayla Ho Lab Performed 03/11/15 & Lab Report 04/07/15 Abstract: Using solutions of sugar and water alongside cola, density and percent sugar can be related. The purpose of this lab is to discover how and with what benefit these factors can be related. Using assorted measurements and the standard curve of the calculated densities and percentages of sugar solutions, it was learned that cola

11, 2013 Title: Laboratory Techniques and Measurements Purpose: To gain knowledge about the International System of Units and use it to determine volume, mass, length, and temperature. To learn to use these forms of measurement to determine density and concentration, as well as learning basic lab equipment to create dilutions. Procedure: Part 1: After reading the various information given, I gathered different objects and measured them using both centimeters and millimeters then converted

compaction test using standard effort on the same soil at different moisture contents. When the density of the soil is plotted over moisture content, a concave down curve is generated. This is because adding moisture increases density until it reaches its optimal moisture, then adding further moisture decreases density. Understanding the relationship between moisture and density is important because density is related to the strength of the soil. Procedure: Testing was done in Brookings, South Dakota
